Abstract

This paper presents a new method that estimates the relative selles-concentration of an industry over both domestic and foreign sellers in 14 OECD countries, on the basis of a joint Structure-Performance and Brander-Krugman type model. Results suggest that overall seller-concentration is significantly lower than domestic concentration in only 7 out of 25 ISIC industries. In most other industries the two indexes appear to be very similar. However, foreign exporters contribute up to 40-50% in determining market structures, especially in Europe. Finally, in most of the highly-penetrated industries, relative selles-concentration did not decrease over the 1971-1994 period suggesting that openness did not enhance competition in OECD markets.
